Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that an article or terminal device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such article or terminal device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the article or terminal device comprising the element.
[0020] Valves are common components for controlling the interruption or opening / closing of pipelines in the chemical industry and daily life. Commonly, there are electronically controlled valves with manual control, semi-automatic control, and automatic control. In a chemical production workshop, the valves in relevant pipelines cannot achieve automatic control. Their installation positions in the workshop are relatively low or concealed, requiring operators to bend down for operation, and some need to be adjusted multiple times, increasing the labor intensity of the operators and prone to causing damage to the operators' lumbar muscles. Therefore, there is an urgent need for a tool or wrench for assisting in adjusting valves, enabling operators to operate the valves at a relatively higher position relative to the valves, facilitating the use by operators, and thus protecting the physical health of the operators.
[0021] The utility model provides a wrench for a circulating water pipe valve, which includes a jaw 1, a jaw base 2, a torque arm 3, a handle 4, and a torque monitoring device. The jaw 1 is a columnar structure with a preset thickness. The jaw base 2 is conical. The first end of the jaw 1 includes at least a pair of jaws arranged oppositely along the circumferential direction. The second end of the jaw 1 is connected to the conical bottom of the jaw base 2. The torque arm 3 is movably inserted through the conical top of the jaw base 2. The handle 4 is connected to the torque arm 3. The handle 4 is a disc structure, a ring structure, or a cross structure. The digital display controller of the torque monitoring device is arranged at the geometric center of the handle 4. The torque sensor of the torque monitoring device is connected to the jaw 1. The jaw base 2 includes one or more segments.
[0022] As Figure 1As shown, the first end of the columnar jaws 1 is provided with a circumferentially opposite jaws, which are arranged to match or clamp with the valve, the second end of the jaws 1 is screwed or sleeved with the conical jaw seat 2, and a torque arm 3 is arranged at the top of the jaw seat 2. The operator rotates the handle 4 to drive the torque arm 3 to rotate, so that the bottom jaws 1 rotate, and the valve and the side of the jaws are against each other, so that the valve is twisted into a certain angle. The conical jaw seat 2 lengthens the distance between the torque arm 3 and the jaws 1, so that the user can operate the valve through the wrench at a higher position relative to the valve, which is convenient for operation. In addition, the handle 4 of the disc structure or the ring structure is more labor-saving to operate than the handle 4 of the lever type; and a torque monitoring device is arranged at the geometric center of the handle 4, and the torque sensor at the jaws 1 monitors the magnitude of the force or the angle of rotation of the valve, thereby improving the valve control accuracy. That is, the valve wrench provided by the utility model is not only easy to operate, but also can control the opening and closing degree and control accuracy of the valve.
[0023] Among them, the aforementioned torque arm 3 is movably inserted into the conical top of the clamp seat 2. The movable setting is for the convenience of adjusting the torque on the one hand, so that the operator can adjust it to a more labor-saving position and then rotate it during operation; on the other hand, it can avoid the surrounding parts when applicable according to their positions, thereby increasing the practicality of the wrench.
[0024] In some embodiments, a lasso 5 is further included, and the lasso 5 is threadedly connected to the outer wall of the jaw 1.
[0025] like Figure 1 As shown, the lasso 5 is arranged on the outer wall of the jaw 1 and is screwed thereto to fix the relative position of the jaw 1 and the clamp seat 2 to prevent the jaw 1 from falling off the clamp seat 2. Alternatively, the lasso 5 can be arranged at the connection between the jaw 1 and the clamp seat 2.
[0026] In other embodiments, the cone of the front clamp seat 2 includes a pin hole, and the pin hole is set to allow a pin to pass through after the other clamp seats 2 are sleeved with the bottom clamp seat 2, and the pin includes a lock buckle. Through the way of sleeve fixing with the pin hole, it is convenient to stack multiple clamp seats 2 to increase the height and facilitate the operator to operate the valve at the extreme position. The lock buckle is used to fix the position of the lock pin, and the lock buckle can use a clamping lock buckle or a wire knot lock buckle, which is not specifically limited in this embodiment.
[0027] In some embodiments, the clamp seat 2 further comprises an L-shaped adapter, the short side of the L-shaped adapter is connected to the cone top of the clamp seat 2, and the long side of the L-shape is connected to the torque arm 3. Figure 2 As shown, the L-shaped adapter changes the direction of the clamp seat 2, which is convenient for valves in some positions. When the wrench cannot directly touch the valve from the top of the valve, it can be inserted from other positions and the L-shaped adapter can be used to change the force direction.
[0028] In some embodiments, the aforementioned jaw 1 includes a double - threaded internal thread, and one end opposite to the tiger's mouth is a jaw plate 6, and the jaw plate 6 includes polygonal holes of at least two specifications. As Figure 3 shown, the jaw 1 that can be installed bidirectionally has one end configured to include a structure with a tiger's mouth, and at the other end of the jaw 1, a jaw plate 6 with holes of various specifications is provided, which is used to match with hexagonal nuts, etc., for opening the external nuts in valves or nuts in other positions.
[0029] It can also be implemented that the surface of the aforementioned handle 4 further includes diamond patterns or anti - slip bands. The diamond patterns and anti - slip bands on the handle 4 are used to increase the friction between the operator's hand and the handle 4, preventing the hand from slipping off the handle 4 and making it inconvenient to apply force.
[0030] Finally, the present utility model provides a wrench for a circulating water pipe valve, including a jaw 1, a jaw seat 2, a torque arm 3, a handle 4, and a torque monitoring device. The jaw 1 is a columnar structure with a preset thickness, the jaw seat 2 is conical, the first end of the jaw 1 includes at least a pair of tiger's mouths arranged oppositely along the circumferential direction, the second end of the jaw 1 is connected to the conical bottom of the jaw seat 2, and the torque arm 3 is movably inserted through the conical top of the jaw seat 2; the handle 4 is connected to the torque arm 3, and the handle 4 is a disc structure, a ring structure, or a cross structure; the digital display controller of the torque monitoring device is arranged at the geometric center of the handle 4, and the torque sensor of the torque monitoring device is connected to the jaw 1, and the jaw seat 2 includes one or more segments. The valve wrench provided by the present utility model is not only convenient to operate, but also can control the opening and closing degree and control accuracy of the valve.
